BOAT.

Specification of Letters Patent.

Application filed November 17, 1908.

Patented April 20, 1909.

Serial No. 462,997.

To all whom it may concern:

Be it known that I, GLENN WVHITE, a citizen of the United States, and aresident of Ashtabula, in the county of Ashtabula and State of Ohio,have invented new and useful Improvements in Boats, of which thefollowing is a full, clear, and exact description.

My invention relates to boats, and it has for its object to provide aboat with a series of hydroplanes which are spaced apart and are pivotedto the bottom of the boat, there being means provided to hold thehydroplanes in operative position.

Another object of the invention is to provide an improved form ofhydroplanes.

Still other objects of the invention will appear in the followingcomplete description.

In this specification I will describe the preferred form of myinvention, but it will be understood that I do not limit myself thereto,as I consider myself entitled to all forms and embodiments of theinvention which may be held to fall within the scope of the appendedclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures, in which' Figure 1 is a sideelevation of my invention; Fig. 2 is an enlarged transverse sectionalview thereof; and Fig. 3 is an enlarged plan View of one of thehydroplanes, a portion being broken away to show the manner of itsconstruction.

By referrin to the drawings, it will be seen that the body 1 of the boatis of the usual form, although preferably it is in the general shape ofan auto-boat, with a fiat bottom 2, and straight downwardly convergingsides 3. To the bottom of the boat are pivoted a plurality ofhydroplanes t, each of the hydroplanes being wedge-shaped and beingpivoted to the bottom of the boat at the apex of the wedge; the top 5and bottom 6 of the hydroplane being flat and the bottom 6 of thehydroplane being longer than the top 5, so that the rear end 7 of thehydroplane will form with the bottom 6, an acute angle.

Each of the hydroplanes is preferably construoted of galvanized iron andis air-tight. A rod 8 is secured to each of the hydroplanes near itsapex by which it is pivoted to the bottom of the boat. Ears 9 project ateither side from the tops and the bottoms of the hydroplanes, and theseears have orifices 10 therein, in which rods 11 are disposed, the rods11 being secured to the bottom of the boat and having threads thereonand nuts 12 which mesh therewith, the nuts 12 bein adapted to screwagainst the ears 9 to hold the hydroplanes at a predetermined angle withreference to the bottom of the boat. A propeller shaft 13 is so disposedwith reference to the boat that the propeller 14 will be under water atall times even when the water line is at the dotted line 15, which isthe case when the boat is under way, the line 16 showing the water linewhen the boat is at rest. hen the boat is driven through the water, thehydroplanes 4 tend to lift the boat from the water and when the boat ispropelled at a sufficiently high rate of speed, the boat will be liftedcompletely out of the water, only a portion of the hydroplanes beingsubmerged.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A boat, a hollow, air-tight, Wedgeshaped hydroplane pivoted to thebottom of the boat, and means for holding the free end of the hydroplanein a predetermined position with reference to the boat.

2. A boat, a hollow, air-tight, hydroplane pivoted to the bottom of theboat, and means for holding the free end of the hydroplane in apredetermined position with reference to the boat.

3. A boat, and a hollow, air-tight, wedgeshaped hydroplane secured tothe bottom of the boat with its top forming an angle therewith.

4. A boat, and a hollow, air-tight, hydroplane seoured to the bottom ofthe boat with its top forming an acute angle with the bot tom of theboat.

5. A boat, a wedge-shaped hydroplane secured to the bottom of the boat,and a top forming with the bottom of the boat an acute angle.

6. A boat, and a hollow, air-tight, wedgeshaped hydroplane secured tothe bottom of the boat with its apex in contact therewith and its uppersurface forming an acute angle with the bottom of the boat, the rear endand the bottom of the hydroplane forming an acute angle.

7. A boat, and a series of hydroplanes secured with their upper surfacesdisposed at angles to the bottom of the boat, the length of each of theinner hydroplanes being sufficient for it to fill substantially the gapbetween the neighboring hydroplanes.

8. A. boat, a series 01"- hydroplanes pivoted to the bottom of the boat,the length 01" each of the inner hydroplanes being sufficient for it tofill substantially the gap between its neighboring hydroplanes, andmeans for securing the hydroplanes with their upper surfaces at desiredangles to the bottom of the boat.

9. A boat, and a series of hollow air-tight hydroplanes secured to thebottom of the boat, the rear end and the bottom of each of 15 thehydroplanes forming an acute angle, the length of each of the innerhydroplanes being SI'l'lllClGllt for it to fill substantially the gapbetween its neighboring hydroplanes,

in testimony whereof I have signed my 2 name to this specification inthe presence of two subscribing witnesses.
